Hose-connector.



JAMES FENTRESS, OF HUBBRD WOODS, ILIIINOIS.

HOSE-CONNECTOR.

To all 'whom t may concern.'

Be it known that I, JAMES FnN'rnEss, a citizen of the United States, residing at Hubbard Woods, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hose-Connectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hose connectors and has for an object to provide a rubber or like elastic connector connected to the end of a flexible coupling or hose, designed for connecting the hose to a nipple and embodying improved features of economy, and reliability of action.

A further object of the invention is to provide a connector eliminating a large portion of the usually expensive material from which such connectors are made, Without detracting from, but rather adding to the eiliciency of such connector.

A further object of the invention is to provide a rubber or other elastic outer connector member with a wooden or metallic core, such core being proportioned to receive the smaller end of the usual and ordi.- nary connecting nipple.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as Will be hereinafter moreV fully described and claimed.

In the drawings r--Figure l is a View in side elevation of the improved connector. Fig. 2 is a longitudinal sectional view through the connector and also showing a longitudinal section of a nipple. Fig. 3 is a perspective view of the core constructed of Wood or similar material. Fig. lA is a vieW in side elevation of the core constructed of resilient material.

Like characters of reference indicate corresponding parts throughout the several views.

In the ordinary construction of connectors for iiexible tubing such as gas tubing it is customary to employ a rubber sleeve circular in cross section and tapered at both ends, having an axial bore of substantially the same diameter throughout and With a Wooden plug having a central opening inserted in one end, the other end being adapt- Specication of Letters Patent.

ed to be forced over the reduced end of a nipple.

To construct the connector of the type just mentioned of sufficient strength to withstand ordinary use, it is necessary to employ a considerable quantity of rubber and to make the connector thick, especially at the center. As rubber is high in price connectors have not been made of material pure in quality and are therefore inefficient in operation. The present invention is designed to employ but a small amount of the expensive rubber but to construct a connector fully as efficient as one containing more rubber'. To accomplish this purpose a core 10 is employed having a central bore ll large enough to receive the end of the nipple l2. The rubber connector member is provided with a thin sheet 13 to surround and embrace the core l0 and to form an air-tight or gastight connection therewith, and with a thickcned portion 14 into which the nip-ple l2 may be inserted, such thickness being required to provide sufficient elasticity to properly grip the nipple. As the nipple is inserted into the Wooden core l0, any side or lateral pressure exerted upon the connector will fail to fracture the rubber material and such device will be subject only to a longitudinal pull. As such longitudinal pull will come upon all the material of the connector, only a small amount of material will withstand considerable of such strain.

Instead of constructing the core of Wood as shown at l0, it is also desirable to make it of metal, as shown at 15 in Fig. 4. Such metal core is preferably provided at its larger end with V-shaped longitudinally extending slots 16 whereby the extremity of such core may be expanded and will contract as occasion may require. Like the core shown at l0 the core l5 is capable of receiving and accommodating the smaller end of the nipple l2.

1. In a hose connector, an elastic envelop having one end proportioned to engage a nipple and a rigid core embedded in the envelop having a bore larger than the normal diameter of the bore of the envelop said core extending at one end beyond the envelop and reduced to form a nipple.

2. In a hose connector, a rigid core having an axial bore and terminating at one end in a reduced nipple, and an elastic enand presenting a hole normally smaller in diameter than the bore of the core and adapted to expand to receive a tapering nipple.

In testimony whereof I aiiix my signature in presence of two Witnesses.
